In CAD, everything fits. There is no friction, no heat, no fatigue, no oil, no time pressure. But a product does not live on a monitor — it lives in hands, on a workbench, in a factory, in a service van, with a customer.

That is why good design does not start with software, but with respect for touch and movement. Human factors are not an afterthought — they are reality.

What an engineer cannot feel in CAD

  • that a wrench actually needs two millimeters more space
  • that an operator does not have a third hand
  • that sharp edges are not a “detail” but skin
  • that a hand never moves perfectly straight

A product that assembles comfortably lasts longer.
A product that is pleasant to service remains appreciated.

The question is always:

How does this feel for the person who will have to do this?

If you can answer that — visually, physically, intuitively —
you are not just designing products, but experiences.

In a world full of automation, the human hand remains the ultimate reality check.
